Alfie Barker, a forward with the semi-pro English soccer team Hitchin, sent some truly sick tweets to Bournemouth star Harry Arter after the Cherries’ 3-3 draw with Arsenal Tuesday night.

And the Southern League Premier Division club has now terminated his contract, effective immediately.

Barker, who had been on loan at South Midlands League Division One team Codicote, issued a groveling apology about the vile messages he sent regarding Arter’s stillborn child, which Bournemouth reported to Twitter.

Arter, whose fiancee, Rachel, is due with another child in February, read the posts after last night’s match and was understood to be deeply upset.

Barker only deleted the tweets Wednesday morning – and he then wrote: “I’m sorry for every comment made.

“I’d like to apologise to Harry Arter and his family for such disgraceful comments and I’m sorry from the bottom of my heart.”

Barker, who has ADHD, said he had consumed alcohol before the tweets.

“I was watching Arsenal at home and I was hyper. At 3-0 down they weren’t playing well and I was annoyed,” he told BBC.

“I’d had a couple of beers and was frustrated at the way the team was playing and I just lashed out. I have no idea why I focused on Harry Arter and his family and I am so, so sorry for what I have done.

“It was a moment of madness. It’s the worst thing I’ve ever done in my life, but it is so out of character. I honestly don’t know why I did it.”

The Football Assocation launched a probe about Barker’s tweets.

And a Hitchin statement read: “Alfie Barker was registered to play for Hitchin Town in the Southern League and has appeared only briefly for the club in the 2016-17 season.

We are disgusted & appalled at comments made by our loan player. We will work with the FA & other authorities on an appropriate solution.

“He has been playing at Langford and Codicote on a dual registration basis.

“The club adopts a responsible approach to social media and would expect any player connected to Hitchin Town to do likewise.

“In the light of the player’s irresponsible and anti-social behaviour, we are terminating Alfie Barker’s registration and relationship with the club with immediate effect.

“We would reiterate that Hitchin Town, as a community club with established links with various segments of the public, has been a long-time user of social media channels and expects all club stakeholders to use them appropriately.”

Hitchin boss Mark Burke had earlier said: “I’ve seen the tweets and I’m disgusted with them. They’re vile and I can’t condone them in any way.”

Barker’s loan club, Codicote, also commented: “We are disgusted and appalled at comments made by our loan player.

“We will work with the FA and other authorities on an appropriate solution.”

Barker’s Twitter account has since been deactivated.

Arter famously starred in a 2-1 win over Manchester United just days after Renee’s death, but now admits he should have taken time off to grieve properly.

The Ireland international – who has a tattoo on his right forearm in tribute to Renee – said last month: “I wasn’t in a good place around that time.

“Physically I wasn’t great – I think stress takes a lot out of your body and I was always picking up little injuries – while mentally I was completely in the wrong place.

“Every day I think of her.

“And it’s strange because there are days when I feel like a normal person, or how someone who hasn’t lost a baby would feel.

“But then it will just hit you, driving along and suddenly you see something that triggers your mind.”
